'SHUTTER-FASTENER.

SPECIFICATION forming part of Letters Patent No. 588,37 5, dated August17, 1897.

Application filed May 26,1897.

To all whom it may concern; I

Be it known that I, ERNST AXTHELM, aciti'- zen of the United States ofAmerica, residing at Pittsburg, in the county'of VAllegheny'and State ofPennsylvania, have invented certain new and useful Improvements in.Shutter- Fasteners, of which the following is arspeciiication, referencebeing had rtherein to the accompanying drawings.

This invention relates to certain new and useful improvements in shutter-fasteners, and has forV its object Yto construct a fastener for thispurpose that will be extremely simple in its construction, strong,durable, and effectual in the'performance of'all its functions.

Briefly described the invention consists ofv a plate which iscountersunk in the shutterrail, so as to bring the face of the sameflush with the face of the shutter, said plate being provided with adepressed portion, which forms a catch to operate the shutter and alsoforms a bracket from which the gravity-catch is suspended, saidgravity-catch protruding through the plate and adapted to engage in asocket provided therefor in the Window-sill; and to this end theinvention consistsr in the novel construction, combination,andarrangement fparts to beherein after more specically described, andparticularly pointed out in theclaim.

In-de'scribing lthe invention in detail reference ishad to theaccompanying drawings, formingapartfof this speciicatiomand Wherein likeletters of reference indicate vsimilar parts throughout the severalviews,in which- Figure l-is'a sideelevation of a portion ofa.building,showing my improved fastener in position. Fig. 2 is a frontView of Vthe fastener.` AFigf is a rear view of the same. Fig. 4 is aside view showing the movement of the gravity-latch in dotted lines.Fig. 5 is a crosssectional View of the fastener and a portion of thewindow-sill and shutter-rail. Fig. Gis a perspective'lview of thefastener. Fig]v is a perspective viewf of the locking-plate for thegravity-latch. Fig. 8 is a top plan view of the fastener. i

Referring now to the drawings by referprovided with suitablescrew-holes?) o, countersunk on the front of the plate, so as to permitthe screw-head to be perfectly iiush with Serial No- 638,282. (Nomodel.)

i the*i face of the plate. This plate is also coun- 'tersunk in theshutter-railc, which is pro- I vided with a recess CZ to receive thedepressed Aportion c of the plate, the opening f thus formed in theplate serving as a catch to operate the shutter. To the back of thisdepressed portion e. is secured, by means of a rivet g, a plate h,having a slot h to permit the vertical movement of the plate, said platehaving a protruding upper end 7o extending through theslot or openingformed in the plate and forming a inger-catch,' by means 'of which thelatchV may be lifted when it is desired to release the same from itsengagement. VThis plate h carries a shank l, which operates in akeepermon the back of the plate a, said shank having formed integral therewith`the catch or l1'o ok mrwhich protrudes through a slot 0 in the plateand is provided with an inclined face n', so as to cause the same tolift the latch when it comes in contact with the plate p, secured in theWindow-sill q and provided with a slot p' to receive the said'hook orlatch.

The operation of my improved shutter-fastener is as follows: Assumingthat all parts have been securedin their respective positions and thefastener attached to the shutter-rail, the shutter being open, as isshown in Fig. l of the drawings, theoperator can close the shutter byinserting the finger in the'opening f without engaging the protruding catch 7o, and as the inclined face n of the hook or catch n comes incontact with the plate p the latch will again fall by reason of its oWnWeight and the hook thereof firmly engage the plate p, so as to securelylock the shutter.

When it is desired to unlock and open the shutter, the operator wheninserting the finger in the opening f places the same in a manner toengage and lift the catch la, which serves toA raise thejcatch out ofits'engagement with the-locking-plate p, and the shutter may be readilyforced open. By this construction it will be observed that when theshutter is closed the lock will operate automatically Without anyassistance fromthe operator, and it will also be' noted that variouschanges may be made Ain thev details of construction withoutdepartingfrom the general spirit of my invention.

IOO

tegrnl therewith a catch or hook and protruding' through said slot inthe base-plate, Said Catch or hook having nn inclined face, and Ineenswhereby said fasten er is secu red to the shutters, substantially asshown and described.

in testimony whereof I affix my signature in presence of two witnesses.
